Relationships defined by _item_related.function_code

Code Meaning
alternate The item identified in _item_related.related_name is an alternative expression in terms of its application and attributes to the item in this definition
alternate_exclusive The item identified in _item_related.related_name is an alternative expression in terms of its application and attributes to the item in this definition; only one of the alternative forms may be specified
convention The item identified in _item_related.related_name differs from the defined item only in terms of a convention in its expression
conversion_constant The item identified in _item_related.related_name differs from the defined item only by a known constant
conversion_arbitrary The item identified in _item_related.related_name differs from the defined item only by an arbitrary constant
replaces The defined item replaces the item identified in _item_related.related_name
replacedby The defined item is replaced by the item identified in _item_related.related_name
associated_value The item identified in _item_related.related_name is meaningful when associated with the defined item
associated_esd The item identified in _item_related.related_name is the standard uncertainty (estimated standard deviation) of the defined item
